MACHINE FOR DRESSiNG HOOPS.

SPECIFICATION forming part of I-.etters Patent No. 267,378, dated November 14,' 1882.

Application filed August 7,1882. (No modeLl To all whom it may concern:

Beit known that I, NATHAN P. STEVENS, of Concord, in the county of Merrimack, of the State of New Hampshire, have invented a new and useful Improvement in Machinery 1 for Dressing Hoops; and I do hereby declare the same to be described inthe following speciiication and represented in the accompanying drawings, of which- Figure l is a top view, Fig. 2 a side elevation, Fig. 3 a rear end elevation, and Fig. 4 a longitudinal section, of a machine embodying my invention.

This machine is designed for use with mech- 15 anism for sawing barrel-hoops from what are termed hoop-poles,77 and may have attached to or arranged near it machinery for such purpose, it being to plane or dress the sawed side of the hoop.

The nature of the'invention is dened in the claim hereinafter presented.

In the drawings, A is the machine-frame, it having suitably applied within it a shaft, B, provided with a driving wheel or pulley, C. Z 5 There is also xed on such shaft, concentrically with it, acutter-wheel, D,which is conoidal, or

approximately so, in form, as shown, and at its periphery is furnished with cutters. The wheel projects somewhat above the frame A, the flat 3o or larger side of the wheel being arranged next to a stationary rest, E, which extends across the frame, is beveled at its upper edge, and,besides,is arched or crowned at top in correspondence with the periphery of the cutter- 3 5 wheel.

In rear of the cutter-wheel are two guiderollers, a c, and two pressure -rollers, b b, arranged as represented, there being in front of the rest E two other guide-rollers, c c, and in 4o advance of them a delivery-roller, d, and two pressure-rollers, e e, these latter rollers being arranged immediately over the delivery-roller.

Each of the aforesaid rollers is supported by an elastic bearing-yoke, f, which, U-shaped,

4 5 as shown, has its prongs secured at their ends in the frame. This elastic bearing-yoke is not only to support the roller so that it may revolve, but is to enable the roller to readily achoops sawed by the two saws.

commodate itself to the hoop, as the latter may vary in thickness. But one set of guide-rolls, 5o a c, and pressure-rollers, b e, need be used with the cutter wheel, the stationary arched rest, and the delivery-roller; but two sets, arranged as shown, fare advantageous when the sawing machinery has'two endless band-saws, with 55 the dressing-machine disposed between them, as with this arrangement the single cutterwheel and stationary rest will answer, with the two sets of rollers, to effect the dressing of the 6o In operating with the machine a hoop is to be introduced, sawed side down, between one of the guide-rollers and its pressure-roller, in rear of the cutter-wheel, and is to be pressed forward over the cutter-wheel and upon the sta- 65 tionary rest, and thence upon a guide-roller, c, and between the delivery-roller d and one of its pressure-rollers, e. The cutter-wheel, being supposed to be in revolution,will cut or dress the hoop transversely thereof as it may 7o progress, and the stationary rest will keep it in its due relation to the cutter-wheel.. The rear pressure-roller will bear the hoop down upon the rest, and will accommodate itself to the hoop as the latter may increase or decrease 7 5 in thickness.' The delivery-roll and itspressure-roller will advance the hoop after it may be received between them, and the hoop as it may advance will be plaued or dressed on its sawed side,which side, after being so dressed, 8o will be slightly concave transversely of it. An endless belt, h, going around the deliveryroller at its middle, and also around the shaft, serves to revolve the said roller.

I am aware that in ordinary planing mech- 85 anisms having acutter-cylinder there isin front lof such cylinder a bearing plane surface to support the board to be planed, and therefore I do not claim such. A rest or surface of the kind would not answer when a cutter-wheel 9o as hereinbefore described is used to cut the hoop transversely, for the rest for such a wheel has to be arched or crowned, as explained, in order for it to properly sustain the hoop relatively to the wheel, and, besides, it generally 95 should be beveled, as represented, in order for it (the said rest) to allowthe hoop passing over tween such rollers, an arehed rest disposed in it to advantage. front of such wheel and to support the hoop, ro

I claimsubstantially as set forth. In combination with one or more sets of NATHAN P STEVENS guide, pressure, and delivery rollers, arranged as set forth, and with aontterwheel arranged Vitnesses:
